Question

tlg ya no 18 pakai cara makasih

Answer 1

Keliling = 2 π r
100,48 = 2 x 3,14 x r
100,48 = 6,28 r
r = 100,48/6,28
r = 16 cm
tinggi krucut
t = √34² - 16²
  = √ 1156 - 256
  = √ 900
  = 30
volume krucut
v = 1/3 x π x r² x t
   = 1/3 x 3,14 x 16 x 16 x 30
   = 3,14 x 256 x 10
   = 8038,4 cm³
